Of course, but that's what history is: hindsight. We can judge based on what we know now. And the judgement is sometimes very kind and quite often isn't. I'm quit often careful with judging because of precisely the reason that you state here. Many mistakes are made because of the level of knowledge at the time. But some mistakes could have been avoided because the one in charge should have known better. In the case of Haig (sorry fastmongrl) the battle of Verdun had been raging for quite some time. That battle had clearly demonstrated the ineffectiveness of artillery on defense positions. The Germans had suffered enormously because of that. The attack plan on the first day of the Somme clearly shows that either Haig was totally ignorant of this, which would be outrageous, or he totally disregarded it, which means he was not willing to learn, which was not much better than the first option.Well said Redcoat. Modern criticism of military leaders is easily done with the gift of hindsight.
Haig Harris have been demonized but, I always ask the question 'what would you have done in the same situation if you were General Haig or Bomber Harris?'
I usually don't get a sensible answer to that... because IMHO there isn't one.
What I would have done is irrelevant, I'm not a general and I'm not trained as one. In my work I am an annalist and 'm doing that here, too. Adding pieces of evidence together and drawing a conclusion. It is my conclusion and you may disagree, that's what the forum is there for.
